specification of Letters Patent.

Patented July 24, 1906.

Original application filed May 26, 1905, Serial No. 262,350. Divided and this application iiled'August 14, 1905. Serial No. 274,033.

To all whom, it may concern:

Be it known that I, JOHANNES TH. FEDER- sEN, a citizen of the United States, residing at Woodside, in the county of Queens, city and State of New York, have invented an Improvement in Lubricators, of which the following is a specification.

My invention relates particularly to the class of oil-feeding devices or lubricators especially adapted to supply lubricating-oil to the machinery of motor-vehicles, motorboats, &c., and the same is adivision of my application for Letters Patent, filed May 26, 1905, Serial No. 262,350, the object of my present invention being to provide a lubricator of simple construction and in whichv springs, check-valves, and other small and uncertain arts that are liable to get out of order are lspensed with.

My invention relates particularly to the sight-feed devices of these lubricators, and in carrying out the same each sight-feed is provided with a regulatable oil-feed controlling the quantity of oil delivered to be forced to the machineryl and with means for returning the surplus thereof to the oil-receptacle. The parts are separable and are easily taken apart for cleaning. The number of feed devices and discharge-pipes agree with the number of places to be lubricated, and their construction and operation are hereinafter more particularly set forth.

In the drawings, Figure 1 is avertical lon itudinal section and partial elevation of t e devices of my improvement, at the same time showing a portion of the walls of the receptacle for oil and the cover. Fig. 2 is a plany of the parts shown in Fig. 1 and a section through two of the lubricating devices. Fig. 3 is an elevation and partial section of thedel"vices shown in Fig. 1 and at ri ht angles thereto. Fig. 4 is an elevation o the regulatable sight-feed device or valve. Figs. 5 and 6 are sectional lans, in larger size, through this valve and t e sight-feed devices. Fig. 7 is a vertical section of a modiiied form of my improvement, and Fig. 8 is a sectional plan at about the line :c of Fig. 7 and ofa size to .correspond with Figs. 5 and 6.

a represents part of the side Walls of the receptacle for holdin the oil, and b is a cover of said receptacle, s own in Fig. 2 as connectfit down over the upper edge of the side walls of the body. The sight-feed devices are preferably connected to the cover and extend above the same, and the cover is apertured to receive the metal annuli or rings d, which are secured thereto in said apertures by overturning the lower edge and by their shoulders above the cover.`

c represents the cylindrical sections of glass of the sight-feeds, which fit down into the annuli d, and each of the sight-feed devices is provided with an annulus d at the upper end, which iits over the upper end of the cylindrical section of glass.

In the lower portion of each sight-feed device e represents a thimble centrally receiving the pipe c', the central portion of the thimble being made funnel shape for the dischar e of the oil into the pipe e', and this thim le iits snugly in the lower portion of the annulus d. At the upper end there is also a thimble f, which is of. conical configuration centrally perforated. This thimble comes within the annulus d and extends above the same and is securely held in position by the clamping-nut f which screws upon the outer surface of the thimbledf down to the upper end of said annulus A pipe g passes through the thimble e, through the sightfeed, and u into the timblef, and the upper end thereo at one side is cut away. A pipe 71, also passes vertically through the sightfeed diametrically opposite from the pipe gthat is to sa .through the thimble e and through the t `mblef, with its upper end cut away at one side-and a cap t screws into the upper end of the thimblef to close the same and to serve as a bearing for the valve c, the stem of which is located centrally in an aperture of the said cap, the conical surface of said valve bein received in the conical central portion of the thimblef, the surfaces contacting for aliquid-tight bearing. This valve is provided with a screw-kerf or other means by which the same may be turned by any suitable instrument.

The valves of lthe lsight-feed devices are alike in the preferred form of my invention that is to say, each valve lc is provided with a merging with the aperture 2, and a circumferential by-pass 4, the center of which is in ed thereto by corner-screws and as having a the same horizontal plane with the center of y.groove-inthe under surfacefor the cover to the lateral opening 3. This particular con struction is plainly shown in Figs. l, 2', 4, 5, and 6. Washers 5 are employed between the valve k and cap i. In the drawings it will be noticed that the sections, Fig. 2, through the sight-feed devices and said valve are in the same position as the vertical section, Fig. l-*that is, the right hand of the sight-feed devices shows the lateral opening 3 agreeing with the opening in the pipe g and the left-hand section shows the lateral opening 3 between the pipes g and 7L. Consequently according to the right-hand section oilfiowingup the pipe g'would' all iiow through the lateral opening 3 and the central aperture 2 into-the center ofthesight-feeddevice and away by the pipe e', while' according to the left-hand section no oil would fiow through the laterall opening 3 .andv central opening 2, but all of it wouldflowby the circumferential by-pass LL'andfby the pipe hback into the reservoir. This latter condition is also manifest from the section Fig'. 6, while from the section Fig. 5 it will be seen that part of the' oil going' up by the pipe'gwould flow by the lateraI opening 3 and central aperture 2, and part of the'oil would flow by the circumferential'by-p'ass 4 and pipeL, the

flow being divided. It will=thus be seen'th'at by the simple turning ofthevalve k the flow of oil may be regulatedy atthe will` of the op erator to pass from the reservoir and pipe g` either through the pipe e, and so tothe parts of themachinery to be lubricated, accordingl course-prevent any oilfiowing downthe pipe hiand'returning to the reservoir' and will consequently make unnecessary the circumferential by-pass 4r4 and will compel the oil in regulatable quantities, determined by the turning' of the valve 7c', to pass through the sight-feed into the pipe e. n modification: retained the pipe 71, rather than dispensing therewith, because the same is quitey essential in the construction and for the balanced support of the thimblesf and" e at opposite sides of the sight-feed.

I have shown in Fig. 2 the peripheries of the clamp-nutf and capi as knurled', so that the same may be grasped and turned by the ii'ngersin case .it isessential to'separate the parts of the oil-feed device from one'anot-her andv from they cover of the oil-receptacle, in

which movement the thimbles` e and f, beingy rinly connected by the pipesv gi and h, come away with saidpipes andthe pipe e', leavin the annulus d' alonesecured to the cover, an they may be replaced in the reverse manner.

I' claim as my invention- 1 Inv a lubricating device, the combination withv a support-plate, of a series of sight-feed devices each comprising a cylindrical section I have in this' 2.
